Is it time to upgrade?

• Electrical service & distributionCurrentLast permitted 2025 (1 year ago). City inspection record: COT - LCEL - Electrical Final approved 2026-06-23. Worth reading the permit itself: it names the service but does not read as an increase in capacity, so this may have been a like-for-like replacement rather than an upgrade. Separately from replacement: NFPA 70E expects the arc-flash study to be reviewed at least every five years, or after any change to the service. TC-COM-0725-01336 — Replacing non- operational interconnection breaker within existing switchgear
• Heating, cooling & mechanicalNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2024 solar pv permit is on file (and 2 more like it) — work like this is often folded into a larger permit without being named, so open that record and check its scope before concluding anything. Packaged rooftop units work harder in Tucson than almost anywhere, so 12 to 15 years is a realistic service life rather than the 15 to 20 the industry quotes. Worth confirming from the equipment nameplate rather than the record. Replacing a rooftop unit is also an electrical question: the new unit's minimum circuit ampacity and its disconnect often differ from the old one.
• Fire alarm & life safetyPermitted — completion not confirmedA 2019 permit specifies this work (the permit description states “Automatic Fire Extingshing Sys - INSTALLATION OF STAINLESS STEEL. UNDERGROUND STUB OUT FOR NEW CONSTRUCTION FIRE SPRINKLER SYSTEM; Commercial Fire Sprinkler Systems - Underground Fire Line Supply; Additional Inspections: 1”), but the available record does not show a final inspection. The permit expired without a confirmed final status. Official status: Expired. T19FC00839 — Automatic Fire Extingshing Sys - INSTALLATION OF STAINLESS STEEL. UNDERGROUND STUB OUT FOR NEW CONSTRUCTION FIRE SPRINKLER SYSTEM; Commercial Fire Sprinkler Systems - Underground Fire Line Supply; Additional Inspections: 1
• RoofNot in this windowNothing in the permit records we read for this parcel that names this system. Roof age matters electrically too: it sets what can be penetrated for new rooftop units, conduit, or solar.

A found permit means a lot. A missing one means less. We read the City of Tucson’s own permit file, not a recent extract of it — back to about 2006, and into the 1990s on properties with that much history. Microfiche before then was never fully digitised. Every record links to the city’s official file. A blank line does not say nothing was done: work gets done without permits all the time. The only way to know what is actually installed is to look at it.

What that usually means electrically

• Worth confirming

  Solar was permitted here in 2024. That means there is an existing interconnection, and the main breaker and busbar rating already carry a PV backfeed — so anything else you add (an EV charger, a heat pump) has to be checked against what is left under the 120% rule, not against the service size alone.

• Worth confirming

  A pool or spa was permitted in 2023. Pool equipment brings its own bonding grid, GFCI requirements, and usually a subpanel — and the bonding rules have tightened since, so older installations are worth verifying.

• Era-based check

  A capacity and condition review is the usual starting point before any tenant improvement or added load. The permit record does not confirm this; an on-site inspection is required.

Most recent permit on record for this parcel: 2026-07-16 (TC-COM-0426-00560) — New 2-story Building 3 on a vocational educational campus. Scope includes the building, parking lot, and connection between the second stories of existing Building 2 and new Building 3..

Permit history (29)

How to read the status column: Final / Complete / C of O — city records show the permit was finalized. Issued — the work was permitted, but final completion is not confirmed. Applied / In review / Approved / Fees paid — proposed, not completion. Expired — the permit expired without a confirmed final status. Void / Withdrawn / Canceled — not evidence the work was installed. Any other status is shown exactly as the issuing office records it, without a completion reading.

Record numbers link to the City of Tucson’s official file. Highlighted rows are the ones that imply electrical work or an unpermitted-work finding.

This is an inference from public records — the year a structure was built, how it is classified, and what has been permitted. It is not an inspection, and nothing here confirms what is actually installed at this address. The only way to know is to look in the panel. See an error in this public-record report?
